Specification of Letters Patent.

Patented July 22, 1913.

Application led January 17, 1911. Serial No. 603.052.

To all echom il may concern Be it known that I. ERNEST DE Jotnxo. acitizen of the lvnited States of America. and a resident ofAllentown.'county of Lehigh. and State of Pennsylvania. have inventedcertain new and useful Improvements in Vehicle-'heels, of which thefollowing is a specification. reference being had to the accompanyingdrawings. forming a partl thereof. g

My invention .relates to vehicle wheels,

and particularly to vehicle wheels employing pneumatic or other/tires.and my 1nvention relates specifically to a new and improved means forfacilitating the removal of such pneumatic tires.

In carrying out my invention I employ a laterally removable flange inconnection with the rim of the wheel. and fingers for normalcoengagement with the said removable flange to hold it in position whenthe tire is in place. together with means by which such fingers may bethrown out of `retaining devices. Fig. Q

engagement with the 4flange to permitthe ,lateral removal thereof whenit is desired to remove the tire. Y

My invention also consists in the employment in combination with suchmeans. of means by which the tire is shifted laterally to start theremoval thereof upon the operation 4of the saidfingers as aforesaid.

My invention also consists in many novel details of construction andcombinations of parts, including means whereby the fingers are locked intheir normal positions in engagement with the removable flange to holdit in place, all as will be fully pointed out hereinafter.

In order that my invention may be fully understood I will now proceed todescribe an embodiment thereof. having reference to the accompanyingdrawingsillustrating the same, and will then pointout the novel featuresin claims.

In the drawings: Figure 1 is `a view in transverse section throughtherim and tire of a wheel constructed in accordance with my invention.the plane of section'heing taken through one of the tire operating andis a similar view showing the tire operating and retaining devices inother positions. Fig. 3 is a view in side elevation `of a part of therim portion of the wheel showing one of the tire operating and retainingdevices. Fig. 4 is a detail view looking outward from the interior ofthe wheel toward one of the tire operating and retaining devices. Fig..3 is a view on a reduced scale of the entire wheel. .showing aplurality of the tire and operatingr devices 6C distributed around it.Fig. f is a detail transverse sectional view similar to Fig. 1 showing amodified form in which the locking device and its operating means isemployed but the tire operating means is dispensed with.

The wheel as a whole comprises the usual hub 10, spokes 11e and felly12. The felly may be of wood as is usual. though of course it may be ofother material if preferred. Surrounding the felly is a' rim 13 havingan abutment 11 at one edge thereof.

A fiange 15 is supported by the rim. in proximity to the abutment 14.being held against outward lateral movement hy theV said abutment. Thisliange may he con` veniently slipped into place and he held from lateraldisplacement only by the abut ment, but except under extraordinaryconditions this` flange is not intended to be removable.- It may ofcourse be removed if desired for purposes of renewal or repair. but itis not necessary to remove it when removing the tire. Another fiange 1Gmounted upon t-he opposite edge of the rim 13 is. however. arranged tobe laterally removed whenever it is desired to ,remove the tire. Thisflange is'arranged to be laterally engaged by a pluralityrof'fingers 1T.A suitable'number of these fingers are distrib- 90 uted around the wheelas appears in Fig. 5. any desired number being employed as may be found"necessary. These fingers are 1ndividually mounted about pivots 18suitably cairied by brackets 19 secured to the fellyr 95 of the wheel orelsewhere. the pivots being so arranged thatthe fingers lin moving'about the axes thereof swing laterally with respect to the flange 16 toa position in engagement therewith as shown inFig. 1, and 100 to aposition wherein they will'be clear of the lateral path of movement ofthe` said flange when is being removed as appears in Fig. 2. Thesefingers are connected bjc connecting rods or links 2() with pins 91 ec-T5 centrically mounted upon disks The disks 22 are rotatably mounted insuitable bearings 23 secured to the underside ofthe felly of the wheel.the felly being preferably recessed as is'shown in thedrawings,'to 110receive the bearing brackets, and portions of thedisk's. Operatingmembers in the form ofsihort arms or levers 24 are provided for thedisks byv which they may be axially rofated. lVhen the device is in itsnormal vlacked position as shown in Fig. 1 lines passl'sthrough thepivotal-connections of the il with the operating fingers and theirdisks, 'preferably just cross the axial center Qf 'the disks, whereb aknuckle or toggle lock is effected. By diepressing the levers 24 theselines .pass to the opposite side of the axial center of rotation of thedisks so as to break joint, and thereafter, in the continued downwardmovement of the operating arms 24 and the consequent movements ofrotation of the disks, the fingers 17 will be thrown down to theposition shownin Fig. 2. In this position the flange 16 mayibe'laterally, removed and the tire 25 may be thereupon withdrawn fromits engagement with the rim 13.

While the foregoing construction and arrangement of parts willconstitute a lock for the fingers in the position in which they areshown in Fig. 1, I preferably employ as a matter of safety, anadditional locking means constituting means operating to engage the arms24 when in their upper positions. A simple form of such means is shownin the drawings constituting a pivoted button or latch 26 which may beturned to the position shown particularly in Fig. 4 t0 hold the arms intheir said adjusted positions.

In order to start the removal of the t-ire when the removable flange 16is released, I have shown operating fingers 27l pivotally mounted as at28, and connected by suitable links 29 with other eccentric pins 30 uponthe disks 22. When the disks are rotated as aforesaid to release thefingers 17 from their engagement with` the removable flange 16, 'theseoperating fingers 27 will be rocked about their supports and the upperext-remities thereof in their engagement with the tire between the inneredge thereof and the adjacent edge lo-f the relatively stationary flange15, will operate to slightly shift the position of the tire as is shownin Fig. 2. This will also have the effect of starting the removableflange 16 from its position so that it may thereafter be readily removedby hand. In addition to the device just described constituting a meansfor starting the removal of the tire, it also constitutes an efa fectivemeans for strengthening the parts, avoiding an undue lateral straincoming upon the wooden felly. By the employment thereof the strain ofholdin the removable flange 16 in place isftrans erred from the'supports for the disks 22 to the links 29 which /thus constitutediagonal Stays, as will be readily understood, and indeed I con- Sidersome such means so desirable that where the tire operating vdeviceincluding the fingers 27 and the links 29 are not em. Vployed,- Ipreferably provide special diagonal stays 31 such as are shown in Fig.6, one end of which embraces the axles of the disks respectively, andthe opposite end of which is secured to the rim 13 upon the oppositeside thereof to that upon which the removable flange is mounted, as bymeans of little brackets 32 secured thereto as is shown.

l/Vhat I claim is:

1. In a Wheel the combination with a felly Y a rim and a laterallyremovable flange therefor, of a plurality of fingers pivotally mountedat their inner ends, means pivotally supported on the felly for movingthe said fingers about their pivots into and out of engagement with thesaid flange, tire starting means at the opposite side of the rim andlinks operatively connecting the aforesaid means and constitutingdiagonal stays for the removable flange. o 2. In a wheel the combinationwith a rim, and a laterally removable flange therefor, of a plurality offingers pivotally mounted at their inner ends arranged to enga-ge thesaid flange to hold it in place, and operating` means for moving thefingers out of such engagement, comprising rotatable elements and linkspivoted eccentrically to the said rotatable elements and to the saidfingers.
